Server rất chậm khi user online > 2000
Chào mn, mình đang vận hành 1 VPS, tốc độ truy cập rất chậm khi nhiều người truy cập.
Cấu hình SV:
- Server chạy ubuntu 20, dùng Laradock deploy:
- Mysql 8.0
- PHP 7.4, PHP-FPM
- Redis
- ...
Ram, CPU, Disk vẫn bình thường.
Mình thử cấu hình PM PHP-FPM
pm = dynamic
; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
; CGI. The below defaults are based on a server without much resources. Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 25
; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
pm.start_servers = 10
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 5
; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 20
nhưng vẫn không có gì thay đổi. mn cho mình xin giải pháp cho vấn đề này, tks
